The video is about repairing a crane axle box (faucet cartridge) without using copper washers. The narrator explains that the axle box has a fluoroplastic ring that wears out over time, causing leakage. To fix this, they use a copper wire with a diameter of 1 mm to create a new ring. They wrap the wire around the rod to create several rings, then cut them to size. The narrator also shows how to clean and lubricate the rubber rings and how to reassemble the faucet. They mention that copper washers are the ideal solution, but if not available, the copper wire method is a good alternative.
